GGCX gamma-carboxylates PROS1(25-676) (pro-protein S) (R-HSA-159752) [Homo sapiens]


GGCX (gamma glutamyl carboxylase) in the endoplasmic reticulum gamma-carboxylates eleven glutamate residues on PROS1(25-676) (pro-protein S). MK4 (vitamin K hydroquinone) is oxidized to MK4 epoxide in the process (Berkner 2000; Furie et al. 1999; Stenina et al. 2001; Morris et al. 1995).
